Generic Construction of Dual-Server Public Key Authenticated Encryption With Keyword Search

IET Information Security
In this paper, we propose a generic construction of dual-server public key authenticated encryption with keyword search (DS-PAEKS) from PAEKS, public key encryption, and signatures.

A Multivariate Public Key Encryption Scheme With Equality Test

IEEE Access, 2020
The public key encryption with equality test (PKEET) allows the cloud server to judge whether two different ciphertexts are generated by the same message without decryption. Through this technique, PKEET provides an effective solution for building secure

Quantum Random Oracle Model for Quantum Public-Key Encryption

IEEE Access, 2019
Random oracle model is a general security analysis tool for rigorous security proof and effective cryptographic protocol design. In the quantum world, the attempts of constructing a quantum random oracle (QRO) have been made, such as quantum-accessible ...

Poly-Dragon: an efficient multivariate public key cryptosystem

Journal of Mathematical Cryptology, 2011
In this paper, we propose an efficient multivariate public key cryptosystem. Public key of our cryptosystem contains polynomials of total degree three in plaintext and ciphertext variables, two in plaintext variables and one in ciphertext variables ...

Forward-Secure Public-Key Encryption Scheme Based on SM9 [PDF]

Jisuanji kexue yu tansuo
In the traditional hybrid cryptosystem, an attacker can generate the previously used session key to decrypt session contents encrypted under the session key due to the leakage of the current private key.

Will quantum computers be the end of public key encryption?

, 2017
The emergence of practical quantum computers poses a significant threat to the most popular public key cryptographic schemes in current use. While we know that the well-understood algorithms for factoring large composites and solving the discrete ...

A new public key cryptosystem based on IFS [PDF]

, 2010
Most public key encryption methods suffers from the inability to prove the difficulty of the algorithms, which summarizes under the category of mathematical problems that have inverses which are believed (but not proven) to be hard.
